Application filed November 18V, 1903. Serial No. 181,5 79.

To ctZ whom, t may concern:

Be it known that I, FREDERIC H. MASON, a citizen of the United States,residing at Spokane, county of Spokane, State of Washington, haveinvented a new and useful Improvelment in Valves, of which the followingis a specification.

The principal purposes of my invention are to provide, first, anautomatic valve which closes by the pressure of fluid without thenecessity of a spring or other equivalent power and which does notrequire a by-pass for closing the same; second, a valve which canbeopened against very light pressures and will close quietly under'suchpressure without any chattering, vibration, or resultant water-hammerand under very low pressure with certainty without any mechanical orexternal assistance 5 third, a valve which will automatically open byatmospheric pressure, whether in vertical or horizontal position whenthe fluid-pressure is cut off, thereby draining the valve and thesupply-pipesk to which it is attached, and, fourth, a valve having aninexpensive construction around the bonnet and valve-stem without theuse of a diaphragm, stuffing-box, or packing and preventing any dripfrom the delivery-spout after releasing the valve. y

I will illustrate and describe my invention as applied to an ordinaryvertical self-closing basin-cock for controlling and delivering waterunder pressure but it will readily be understood by those skilled in theart that my invention applies as well to horizontal bibs and faucets andto valves of various kinds and for various purposes used to control,divert, or deliver not only water but fluids and gases of differentkinds under pressure, such as steam, gas, and compressed air.

While I shall describe with exactness and minuteness the preferred form.of construction as seen in the drawings and their Inode of operation, itis by no means to be assumed that my invention as expressed in thebroader claims .is to be limited therefor to the particular contours andassemblage so specifically described. I myself have already devised manymodifications, but embodying the same fundamental lregulating principle,and any skilled mechanic can do the same as soon as he grasps my theoryof construction and use. Their modifications pictorially may be quiteunlike the original, but yet employ substantially the same means,coacting insubstantially the same way to produce substantially the sameresult.

Referring to the drawings, Figure I is a central vertical sectionthrough the assembled apparatus, showing the main valve closed. Fig. IIshows the bonnet in elevation, but the rest of the structure in centralvertical section with the valve depressed and open. Fig. III is a detailin side elevation of the regulating device. Fig. IV is an enlargeddetail, in vertical section, of the main valve and the regulatingdevice. Fig. V is a detail in elevation of the piece constituting thefixed balancing-valve chamber, in which moves the main valve and Fig. VIa like view of the movable balancing-valve.

In the accompanying drawings, 2 is the central or main section or shellof my improved valve. Within the shell is a central depending tube 3',its open lower end constituting the main valve-seat 3 and its upper endmeeting the horizontal passage 4', leading to the somewhat largerdelivery-spout 4. The upper wall of the passage 4 and of the `space 19around the said depending tube 3 forms the bridge 5, which divides thefluidsupply from the bonnet-chamber 18 above it. This chamber 18 has avent extending from the bottom of the same (which is the upper surfaceof the bridge 5l to the spout 4., where it is increased in diameter overthe passage 4. The said chamber 18 is formed between the bridge 5 andthe bonnet or cap 8, which forms the top section of my valve and has thevent 9 open to the atmosphere.

- Reciprocatory vertically within the opening 10 1n the upper end of thebonnet is the shank 11 of the push knob or button 12, secured to theshank by the screw 13. The shank has the packing 141 and the socket 15to receive the upper end of the valve-stem 16 of the main valve 17,which lies below and fits on the valve-seat 3, the said valve-stemextending up through the tube 3', an opening in the bridge 5, and thebonnet-chamber 18.

The chambers 18 and 19 constitute airchambers, the latter of whichreduces the tendency tothe production of a water-hammer by giving thewater an opportunity to ter the valve is seated.

Secured to the bottom of the central section 2 is the lower section 7 ofmy valve, to which section the usual supply-pipe is conl nected in anyapproved manner. Within the travel beyond the inlet and the valve-seataf- TOO section 7 is the valve-chamber 20, also secured to the section2, but preventing fluid from passing from the section 7 into the section2,or the tube 3 therein except by way of the valve-chamber, which has alateral port 21 leading from the section 7 into the chamber 2O at somedistance from its upper end.

- Secured by the screw 22 to the valve 17 is the supplemental valve 23,which is a sleeve slidable on the chamber 20, which is closed below theport 21 by the partition 20. The screw extends tl'. rough the port 21,and in the movements of the valve 23 slides up and down in the port.When the valve 23 is at its upper limit, the port 21 is closed, and atits lower limit open. The lower end of the valve 23 is preferablyclosed, as shown, and the space 24 between the partition or bottom 20and the bottom of the valve forms a dashpot or regulating-chamber forcausing a gradual and controlled closing of the main valve 17.

The 'lit between the valve-chainber 20 and the valve or sleeve 23 willbe closed or loose, according to the condition of pressure, character ofthe iiuid dispensed, &c. The main valve 17 reciprocates within thechamber 20 and is acted on slowly by the fluid-pressure on its underside, owing to the restricted inlet thereto.

The valve or sleeve 23 preferably cuts off the iiuid from the chamber 20just before the main valve 17 reaches its seat 3.

The operation is as follows: The valve being seated, a slight pressureupon the knob 12 l will start the valve 17 from its seat and will movethe valve 23, so as to uncover slightly the side port 21. Thewater-pressure will then bear down on the main valve and counteract theupward pressure to such an extent that a small child can easily open thecock against a much higher pressure than it can.

ever be subjected to. Vhile the valves are moving to opening position,the sleeve or valve 23 is performing an important function, as iluid issucked into the enlarged space or regulating chamber 24, which steadiesand partially balances the main valve 17. When pressure is removed fromthe knob 12, the fluid-pressure against the closed end of the sleeve 23starts it upwardly or in the direction of the How of the fluid. rlheiiuid imprisoned in the chamber 24 having to be expelled therefrom,causing the seating movement of the valve 17 to be gradual, the speed ofthe valve in closing depends upon the closeness of fit between thewallof the valvechamber 20' and the sleeve 23, and changes in such iitcan be made to give varying degrees of speed both in the opening andclosing movements or to comply with the conditions or kinds of fluid andtheir varying pressures, &c. The water which follows the valverod upinto the drainage-chamber is drawn down and awayfthrough the inclinedchannel 6 into the delivery-spout 4 by the attraction of this largerstream as it expands and spreads out in passing from the comparativelycontracted channel 4 to the larger channel leading to the extremity ofdelivery-spout 4. l not only provide a drainage-port in the bonnet, butIalso provide a vent through the upper bonnet which permits theatmospheric pressure to open the valve when Huid-pressure is cut off andalso prevents any drip following the closing of the valve, the entirecontents of the drain-chamberbeing immediately expelled as the valvecloses.

The automatic following ofthe valve 17 or the adjustment of the same tothe natural wear thereof against its seat is important and consistssimply in initially locating the sleevevalve 23 so that there will beextensive space for movement left between the interior of the sleeve andthe end of valve-chamber 2O and between the upper edge of sleeve and theextended upper end of valvechamber where it screws onto or into centralfitting to allow for the natural wear of the valve before these partscome into contact. The sleeve 23 does not have to fit so closely orsnugly as to be liable to clog or stick when the water is muddy orslimy. The vent 9 through the bonnet 8 permits all the fluid which hascrept up past the valve-stem 16 to empty or escape from thedrainage-chamber 18 quickly when the valve closes, as no atmosphericseal can occur at the extremity of the delivery-spout, as always doesoccur where diaphragms, packings, stul'ling-boxes, or the like are usedaround the valve-stems or push-button Shanks. The cut-ofil is positiveand quick and no after drip follows the closing of the valve.

In the leading claims of this application l do not wish details of form,proportion, and location to be implied, but only such limitations uponthe parts as are expressly stated in said claims.
